Abstract
The invention realizes miniaturization, high performance, and informatization of a control device. Only an application not required to be repeatedly executed with respect to a control subject at an execution interval less than or equal to a prescribed time interval is assigned to a fourth core (114) of a PLC (10).
Claims4
A control device, controlling a control subject by repeatedly executing a plurality of control programs at a prescribed time interval, the control device comprising:
- a multi-core processor comprising a first core that is assigned with the plurality of control applications which are repeatedly executed by the control device at an execution interval less than or equal to the prescribed time interval and a second core that is assigned with a plurality of non-control applications which are non-periodically executed by the control device or repeatedly executed by the control device at an execution interval greater than the prescribed time interval, wherein the plurality of control applications and the plurality of non-control applications are assigned to different cores;
- and
- a memory storing the plurality of control programs,
- wherein in the second core, a proportion of CPU bandwidth and memory usage of a total CPU resource assigned to each of the plurality of non-control applications is settable by a user.
